Appendix Appendix A1.1 Study Characteristics: Baenen, Bernhold, Dulaney, and Banks, 1997 (randomized controlled trial) Characteristic Description Study citation Baenen, N., Bernhold, A., Dulaney, C., & Bankes, K. (1997). Reading Recovery: Long-term progress after three cohorts. Journal of Education for Students Placed at Risk, 2(2), 161. Participants The study involved 772 first-grade students who were studied in four cohorts between 1990 and 1994. Of this total number, only one cohort (that received treatment in 1990–91 at 10 schools1) with 168 students meets WWC criteria for inclusion. After 1990–91, the comparison group was made up of students who were not comparable to the intervention group in terms of their achievement levels—they were not the lowest-achieving students in participating schools, as the Reading Recovery® students were. Due to attrition, the authors’ final analysis sample included 147 first-grade students in the 1990–91 cohort.2 All 147 students were followed longitudinally into second grade; 127 of these students were followed and included in the third-grade analysis. No information was reported regarding ethnicity or gender, but all students were low achieving, and a high percentage of students qualified for free or reduced-price lunch (N. Baenen, personal communication, January 9, 2006). Setting The study took place in 10 elementary schools in Wake County public schools in North Carolina. Intervention The intervention group was originally composed of 84 students who qualified forReading Recovery® on the basis of three subtests from the Observation Survey of Early Literacy Achievement—Text Reading Level (running record), Dictation, and Writing Vocabulary. Intervention students, among the lowest-achieving students at their schools, were randomly assigned to receive the Reading Recovery® intervention. They were taught by one of 12 teachers. Results were presented for 72 students for first- and second-grade analyses. Of these, 27% of the students received a “partial program” instead of the full set of more than 60 lessons in Reading Recovery®. Comparison The comparison group was composed of 84 students who qualified forReading Recovery® on the basis of three subtests from the Observation Survey of Early Literacy Achievement—Text Reading Level (running record), Dictation, and Writing Vocabulary. These students, among the lowest-achieving students at their schools, were randomly assigned to a wait list for Reading Recovery® intervention. They did not receive Reading Recovery® during the time of the study but received the regular services available to them. Results were presented for 75 students for first- and second-grade analyses and 68 students for third-grade analysis. Primary outcomes Grade retention was measured at the end of first and second grade, and the North Carolina End-of-Grade test in reading was used at the end of third grade. The authors also and measurement measured referral to special education and Title I services and teacher perception of student achievement, but these outcomes are not included in this report because they are not specified by the WWC Beginning Reading Protocol. The authors used three subtests of the Observation Survey of Early Literacy Achievement, but these measures are not included in the review because collection of these data did not focus on the full sample of students. For a more detailed description of the outcome measures, see Appendix A2.4. Staff/teacher training Reading Recovery® teachers participated in a graduate-level course that included 33 training sessions from September to June of the intervention year. The 1990–91 school year was the first year of implementingReading Recovery® for the district; therefore, it was the first year the teachers taught the intervention. 1. One of the manuscripts related to this study reported 11 schools. 2. Pretest comparability of the students was demonstrated for only 146 students. It is reasonable to assume that the pretest mean for the 146 students would be similar to that based on 147 students. WWC Intervention Report Reading Recovery® December 2008 16 Appendix A1.2 Study Characteristics: Pinnell, DeFord, and Lyons, 1988 (randomized controlled trial) Characteristic Description Study citation Pinnell, G. S., DeFord, D. E., & Lyons, C. A. (1988). Reading Recovery: Early intervention for at-risk first graders (Educational Research Service Monograph). Arlington, VA: Educational Research Service. Participants The study involved 187 first-grade students from 14 schools. Although information about the specific schools included in the study was not presented, the district has a racial composition of 45% nonwhite students and a gender composition of 51% male students. The city has a mobility rate of approximately 20%, and 66% of students receive free or reduced-price lunch. Students in the study were low achieving, as defined by scoring in the lowest 20% of their class on reading measures. Due to attrition, results were reported for 184 students. Setting The study took place in 14 urban public schools in Columbus, Ohio. Intervention There were two intervention groups with a total of 134 students taught by 32 teachers. One group was randomly assigned to receive the standard Reading Recovery® pull-out program (n = 38). These students had regular classroom teachers who were not trained in Reading Recovery®. This group experienced attrition of one student. A second group of students determined to be eligible for Reading Recovery® received the standard Reading Recovery® pull-out program, with the addition of having regular classroom teachers trained in Reading Recovery® (n = 96). The second group was not randomly assigned to Reading Recovery® or to their classroom teacher, so this portion of the study is considered a quasi-experimental design. It is not included in the intervention rating because the second intervention group with a Reading Recovery®–trained teacher as its regular classroom teacher goes beyond the standard implementation of the program.1 Comparison The comparison group was composed of low-achieving students who did not have regular classroom teachers trained in Reading Recovery® and who were randomly assigned to an alternative compensatory program (n = 53) (G. S. Pinnell, personal communication, September 9, 2006). Students in this group received a series of skill-oriented drill activities conducted in small groups or individual sessions of 30–45 minutes from a trained paraprofessional. The comparison group was not statistically different from either intervention group on pretest measures (G. S. Pinnell, personal communication, December 5, 2005). The final analysis sample included 51 students. Primary outcomes Five subtests of the Observation Survey of Early Literacy Achievement were included—Letter Identification, Word Recognition, Concepts About Print, Writing Vocabulary, and and measurement Dictation. Additional measures included a writing assessment, the Reading Vocabulary subtest of the Comprehensive Test of Basic Skills (CTBS), and the Reading Comprehen- sion subtest of the CTBS. Results from the Observation Survey: Text Reading Level subtest were not reported because effect sizes that were comparable to other measures could not be calculated.2 For a more detailed description of these outcome measures, see Appendices A2.1–A2.4. Staff/teacher training Teachers received a full year of special training, during which they practiced teaching and observed other teachers through a one-way mirror. Twelve teachers received training from a university program and were in their second year of teaching the intervention during the time of the study. The other 20 teachers received training from a local teacher leader and were in their first year of teaching the intervention during the time of the study. 1. Results are reported in Appendices A4.1–4.3 2. Findings based on the Observation Survey: Text Reading Level subtest are not included in the effectiveness ratings because effect sizes and the statistical significance of the findings could not be calculated given the information provided in the study. The Observation Survey: Text Reading Level subtest is reported as reading levels based on ordinal, rather than equal-interval, scales. For example, the increase in fluency measured by scoring at level 3 compared with level 2 on the scale may not be equal to the increase in fluency as measured by scoring at level 24 compared with level 23. The author no longer had information on the number of students scoring at each level. For more detail, see Denton, C.A., Ciancio, D. J., & Fletcher, J. M. (2006).

Participants The study was designed to examine outcomes of 403 first-grade students distributed across 43 schools. Percentages of children receiving Aid to Dependent Children ranged between 9% and 42% among districts. For this report, the WWC looked at results for students in 10 districts at schools that were using Reading Recovery®. In those schools, eligible students were randomly assigned
